标题： Cooling and the SU(2) Instanton Vaccuum

摘要： 我们提出对通过使用欠松弛冷却算法冷却后的配置得到的4维纯规范格点$SU(2)$中瞬子性质的研究结果。 我们讨论了校准冷却的方法以及不同冷却程度的影响，并将我们得到的瞬子形状、大小和位置的数据与连续体结果进行比较。 在本文中，我们扩展了我们为用于$O(3)$而开发的想法和技巧，并将结果与其他小组得到的结果进行比较。 显示英文摘要

摘要： We present results of an investigation into the nature of instantons in 4-dimensional pure gauge lattice $SU(2)$\ obtained from configurations which have been cooled using an under-relaxed cooling algorithm. We discuss ways of calibrating the cooling and the effects of different degrees of cooling, and compare our data for the shapes, sizes and locations of instantons with continuum results. In this paper we extend the ideas and techniques developed by us for use in $O(3)$, and compare the results with those obtained by other groups.
